A healthy diet should be followed to keep the person as healthy as possible and to ensure that their weight is kept within normal limits.

A dietician is responsible for initially prescribing the appropriate complete food supplement (enteral feeding), this is a milk which contains the correct nutritional value needed to remain healthy and maintain their weight. The dietician will set up a home delivery service and the parents or carers are then responsible for ordering the supplies needed normally on a monthly basis.

A speech and language therapist can help with any feeding difficulties, including suggestions for making food and drink easier to swallow, this may be through thickening drinks, mashing or pureeing foods. They are also responsible for observing and referring for tests if the person is having difficulty swallowing (dysphagia).
